WSL2 update and apt-get failure, though ping works fine [duplicate]

I am trying to get Ubuntu running using WSL2 on my office laptop.

Problem:When I try to run apt-get update or any install command, eg: apt-get install gcc, it always ends up with 101: Network is unreachable.

Solutions I have tried so far:

1. Firewall

   My initial guess was that my office firewall may be blocking the connection, but on quick ping check I see that it works fine. Also I have browsed the URLs in chrome and it works without any issues.

   $ ping 91.189.91.39PING 91.189.91.39 (91.189.91.39) 56(84) bytes of data.64 bytes from 91.189.91.39: icmp_seq=1 ttl=51 time=256 ms64 bytes from 91.189.91.39: icmp_seq=2 ttl=51 time=256 ms^C--- 91.189.91.39 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1002msrtt min/avg/max/mdev = 255.540/255.757/255.975/0.217 ms

2. resolver configuration file issue.

   I have tried changing the default nameserver to 8.8.8.8 and other DNS providers as well but didn't resolve the issue. Also since ping works, DNS resolver shouldn't be a problem.

Now there are few more solution which I am able to find, like forcing apt to use IPv4, deleting hypervisor switching adapter and other such solutions but their problem doesn't seem to corelate with what I am facing and I don't want to keep shooting arrows in dark.

Any help or direction pointing will be very much appreciated.Thank you
